Driller Posted October 10, 2012 Share Posted October 10, 2012 About to install this G2 plus a power RIO and want to make a really nice job of it. It's going in a server cupboard and so the cables aren't coming through the wall behind IYSWIM but from the side in conduit. What is best practice in this case? Is it accepted to slip the cables in behind the gap left by the spaces on the panel,I'm not sure this feels right somehow. Otherwise what's best practice when coming in from the side, the cutouts on the G2 and RIO never seem to be in the right place, although it could just be me of course. Here's a pic on the "bench" (or dining room table) of what I mean: I will of course strip the insulation back more on the install. Also, is it acceptable to use the 0V common to bridge over to the negative terminal on a PIR using EOL wiring. This is what it shows in the manual but up till now I've always run a separate wire from the Aux-. Link to comment Share on other sites More sharing options...
Lwillis Posted October 10, 2012 Share Posted October 10, 2012 I usually take aux from the aux - not the 0v in the inputs Doesn't make any diff as they are all common anyway . Why are the cables side only could they not be routed into the top knock outs? If not where the rear entry points are , use those / may have to step the panel from the wall slightly or create a bigger space behind the panel Make sure the zones are easy to trace back to the cables - will help during fault finding Link to comment Share on other sites More sharing options...
Driller Posted October 10, 2012 Author Share Posted October 10, 2012 Thanks for the quick reply L- gotta get this in this evening! I didn't want to open the top knockouts because of the possibility of dust ingress (ok I could be being a bit obsessive here) but saying that technically it could get in through the spaces on the back so...I may just do that All cables are pulled, tied and labelled. Thanks again! Link to comment Share on other sites More sharing options...
james.wilson Posted October 10, 2012 Share Posted October 10, 2012 If your using conduit then use an elbow and relevant fittings into the top. Dust will get in from all angles as its not a sealed enclosure securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

norman Posted October 10, 2012 Share Posted October 10, 2012 4 core? wow! Nothing is foolproof to a sufficiently talented fool. Link to comment Share on other sites More sharing options...
Lwillis Posted October 10, 2012 Share Posted October 10, 2012 4 core? wow! Didn't notice that first time around Can you still get 4 core ? I allways use 8 as standard Link to comment Share on other sites More sharing options...
Driller Posted October 10, 2012 Author Share Posted October 10, 2012 Thanks for the tip James, I've got some of those I think. Er...what's wrong with 4 core is it a question of future proofing? Link to comment Share on other sites More sharing options...
james.wilson Posted October 10, 2012 Share Posted October 10, 2012 You can never have too much wire. Often a false economy to use 4 core if using all 4. ie use a 6 or an 8 and have spare. We dont use 4 core usually use 6. Else we would have to stock even more cable types securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

antinode Posted October 10, 2012 Share Posted October 10, 2012 The four core is a little bit tight We always use 8 core, you never know when you'll need the spares. Future additons, damage, doubling up to reduce volt drop etc.The cabling is the hardest part of the install to replace afterwards so it's better to do that bit properly the first time IMO! As for cable entry, I'd recommend you use the top rectangular trunking knock outs. If you bring your trunking down from the ceiling it'll line up nicely. Don't worry about dust, you'll never stop it getting in there. In true Blue Peter style, here's one I made earlier Apologies for the butchered broadband filter but it was a case of getting the job done.

Driller Posted October 10, 2012 Author Share Posted October 10, 2012 Oh right, I wasn't being tight honest just like the minimalist approach, iswym about spares and pulling cable but in this case it's all suspended ceilings so easy to pull later. Next install I'll pull 8 core! Like the idea of conduit and the square knockouts. I'm in there right now trying to get the square knockouts out. What a bugger and I seem to be creating an alarming (sorry) amount of metal dust! How the hell do I get these out and can I leave the PCBs in? Oh yeah and nice photos, control panel porn! If I can achieve anything like that I'll be really happy. Link to comment Share on other sites More sharing options...
9651 Posted October 10, 2012 Share Posted October 10, 2012 Punch them out with hammer/screwdiver/punch. Probably best to take the pcb out. Always do it before you fit it to the wall Link to comment Share on other sites More sharing options...
MrHappy Posted October 10, 2012 Share Posted October 10, 2012 Like the idea of conduit and the square knockouts. Don't, chances are when you replace the controls in the future the metal work on the replacement will be a different type, as post 9 is a much better way Mr Veritas God Link to comment Share on other sites More sharing options...
Lwillis Posted October 10, 2012 Share Posted October 10, 2012 Antinode- Nice. Shame about the error 6 on the dualcom ... Oh sorry ill stand on my head next time !! Wondering why you didn't use the trigger lead tho ? It's still neat tho Link to comment Share on other sites More sharing options...

Driller Posted October 10, 2012 Author Share Posted October 10, 2012 Don't, Whoops, too late. Got the PCBs out (got a GSM module for the G2 anyway so had to) and gave em a good whack, worked pretty well, wouldn't dare hit it with a PCB in though. Right, GSM module to go in and cable connections to be made Oh yeah, how come your G2s are a different way round to mine? Link to comment Share on other sites More sharing options...

Wondering why you didn't use the trigger lead tho ? It's still neat tho Thanks We tend to just stick to the outputs on the panel to be honest. I'm not sure why, we've just always done it that way. It's a "powers that be" thing, I think On G3 jobs there is usually a smart PSU with the panel for the additional outputs. Trade Member Link to comment Share on other sites More sharing options...

Does this relay not also the monitor the radio path also? By the way not picking at you just interested in your opinion as I've done this myself when I've run out of inputs on board.

antinode Posted October 10, 2012 Share Posted October 10, 2012 I can see a few bits wrong but that's only IMO. I'm curious as to what you would do differently? Is flex into fabric of building one of them? Belfastengineer, I think the linefault output is something we need to look into IMO. As above, we monitor the line via the panel, but obviously we don't get notification of GPRS failure at the panel. Maybe the trigger lead is the way forwards...

Maybe the trigger lead is the way forwards... It is. Flexible cables should not be used for fixed wiring but that's only my opinion. Regs have changed to allow flex as fixed due to whine from our European neighbours. So technical wise it's not an issue. Don't dwel on it as I approve and I'm flattered your intrested in my opinion. Telecom test point external to panel would be a must for me and ours get a solwise from risco on every instal Customers! Link to comment Share on other sites More sharing options...
